IMPROVEMENT IN SIDE-STICK AND QJOINS.

Specification forming part of Letters Patent No. 218,518, dated August12, 1879; application filed December 31, 1878.

To all whom it may concern:

Be it known that I, GEORGE T. GosonN, of Keyser, in the county ofMineral and State of West Virginia, have invented a certain new anduseful Improvement in Side-Stick and Quoins and I do hereby declare thatthe following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification.

This improvement relates to printers sidesticks and quoins of that classin which screws are employed in lieu of sliding wedges for locking upthe matter in the chase.

My invention consists, first, in the combina tion of a wide metallic barhaving transverse screw-sockets, two or more quoin-pieces of the sameheight as the bar, forming non-rotary parallel bearings, and acomplement of rotary screws swiveled in the said quoin-pieces, andadapted to turn toward the head of the form in looking up, whereby Iform a simple and efficient side-stick and quoins adapted to restsolidly and level upon the imposing-stone and against the chase, withoutdanger of accidental displacement.

My invention consists, secondly, in a combined indicator and limit-gage,to facilitate the -selection of the proper side-stick and quoins, and toprevent the accidental separation of the parts, as hereinafter setforth.

Figure 1 of the accompanying drawings is a face view of a combinedside-stick and quoins constructed according to this invention for theleft-hand side of a small chase. Fig. 2 is a face view of thecounterpart of the same for the right-hand side of the chase. Fig. 3 isan edge view of said right-hand side-stick and quoins; and Fig. 4 is across-section on the line 4 4, Fig. 2.

Like letters of reference indicate corresponding parts in the severalfigures.

My combined sicle'stick and quoins consists, essentially, of a uniformrectangular bar, A, of proper length for a'given size of chase or form,two or more quoin-pieces, B, presenting extended flat faces to bearsolidly against the chase, and two or more rotary screws, O, unitingsaid bar and quoin-pieces. The screws 0 have angular heads 2 to receivea wrench, and these are provided with axial rivets y, by which saidscrews are swiveled to the quoinpieces B, the latter having countersunkdrillholes to receive said rivets. Said screws project from the outeredge of the bar A, and the latter is made of sufficient width toaccommodate the threaded portion x of screws of the required length inits transverse sockets w, Fig. 4. v

In a left-hand side-stick and quoins, Fig. 1, righthand screws areemployed, and in a right-hand side-stick and quoins, Fig. 2, lefthandscrews are employed, so that all the screws shall turn toward the headof the form in locking up. This greatly facilitates the use of the newdevice, as in the use of ordinary wedging-quoins, and in all otheroperations, printers are accustomed to make their motions toward thehead of the form.

The proper side-stick and quoins can be readily selected by the aid ofan indicator-arm, D, which is attached to the top of the bar A at itsouter edge by a pivotal rivet, '0, at one end of the arm. This at oncedistinguishes the top of the side-stick and quoins, and by the locationof its pivot shows the direction in which the screws turn in looking up,the indicator-arm turning in the same general direction as the screws ofits set, as indicated in Fig. 1.

Said indicator-arm serves also as a limitgage, to show the extent towhich the screws will work, as indicated in Fig. 2, and thus facilitatesselect-ing slugs, reglets, or the like to supplement the side stick andquoins, and also to obviate the employment of other devices forpreventing the accidental separation of the parts.

To provide for usingeither of the side-sticks and quoins upside down inan emergency, the arm D is arranged within a depression, u, so as to beflush with the top of the bar A, its pivot 11 being headed within acountersunk drill-hole in the arm, as shown in Fig. 3.

Besides the distinctive advantages above specified, it will be seen thatmy combined side-stick and quoins will apply the requisite power inlooking up and unlocking a form without danger of disturbing the matter;and owing to the union of all the parts, no time will be lost in itsuse, as in selecting appropriate quoins.

The wide metallic bar possesses the requisite rigidity for perfecttrueness, and, being utilized for the screw-sockets, it obviates theemployment of wide quuin-pieces.

When the parts are extended in locking up, the quoin-pieces operate tokeep the bar level, and at all times they form non-rotary parallelbearings,which lessen the labor of locking up, prevent straining thescrews, and preclude the displacement which might otherwise result fromthe motion of the screws.

The reference-letters A B (J 1) above used are those of Fig. 1, whichshows a left-hand side-stick and quoins, as aforesaid. A B G D representthe corresponding parts of a right-hand side-stick and quoins.

The parts may all be of iron or brass; but preferably the indicator-armwill be made of a distinguishing color.

I know of the scravqnoins shown in Pat ents No. 158,001 and No. 167,780,and of the combined side-stick and qnoins shown in Patent N 0. 173,992,and hereby disclaim the same.

The following is what I claim as new and of my own invention, and desireto secure by Letters Patent, namely:

1. The combination, in a side-stick and quoins, of a wide metallic barcontaining transverse screw-sockets, two or more quoin-pieces of thesame height as the bar, forming non-rotary parallel bearin gs, androtary screws swiveled in said quoinpieees, and adapted to turn towardthe head of the form in looking up, as herein shown and described, forthe purposes set forth.

2. An indicator and limit-gage, constructed and operating substantiallyas herein shown and described, in combination with a side-stick andquoins having rotary screws which turn toward the head of the form inlocking up, for the purposes specified.

G. T. GOSORN.
